land `7, is"mount'edgtransversely olf they' machine, near `one end-it'hereot, in 'suitable bearings, and-fits crank arm'fl` provided with an anti-friction roll,' engages a slotted cross head `18 'securedto a plunger-rod 19 y niou'nt'ed'i'n cross hars l2O and 2l arranged transversely'of vthemachinaso as to recip rocate freely thereinrthe said plunger rod heling provided at itsforivardendv with head- 22 from 4Which extends rearwardly a top Weloor plate' 23 and-side'wvings or plates 24.,

r,llhe said plunger reciprocates inf afmold hox or casing 25, Whichflo'oX, as shovvn'in Figure 7, is'provided inone of itsWalls7 'the upper Jvvall'ashereshovvn', With a -feed opening, which feed opeiiinginthe present embodiment comprises achute 126 y communicating With a ljhutter' board or `pan l2.7 into which the `hutten-or otherinaterial,

plunger rod 19].reciprocate the plunger 22 forward and backward beneath the feed opening and torce forward through the mold box the butter which leeds downwardly into said mold box 25, so that successive blocks orfmasses oi butter will be periodically forced forward through the mold box. The web or ,apronl 23 with which the plunger 22 is provided will, when the plunger moves forward, serve as a' cut-oit plate to prevent the butter working downwardly behind the plunger, said apron'23 being of such length and width as to comprises the broad knife` plate 28 mounted so i as to slide just above and upon the apron 23 of the plunger, said knife being oit such c dimensions as to close the teed opening, and

having` at its forward end vasharp severing edge. The 'said kniteis mounted upon a cross Ablock 29 tov which is secured rods 80,'

two being` shown in the present instance, which extend rearwardly and at their outer ends slide in' bearings 3]. on the cross head 2l heretofore referred to., The rods 30 have spiral springs 32', which are compressed between the cross head 2l and the knife 29, and furnish the driving power for effecting the cutting strokel yof the knife. The said knife is coupled for movement reaiw-'i'ardly with the cross head i8 heretofore referred to by means of a spring latch 33 (see Fig ure 7) which engages the upper end of' the cross head, as shown, in vsuch manner as that, when the cross head and plunger' are moved rearwardly, the knife will be drawn back and the springs 32 put under compression, the said plunger and the Vknife [mov-ing' back together. l/llhen the cross head reaches its rearmost position, as shown in dotted lines in Figure 7, the spring latch 33 will strike with its rear end a tripping projection 34, which will disengage the latch from the cross head, asshown in dotted lines in Figure 7,` and the springs 32 will 4i-i7 in the cross bar' 2l in which, as shown 22 moves forward, forcing the severed block through the rmold box. y*

As the vsuccessive blocks are forced forvward, theywill, et course, smear together and form a continuous bar of butter, which will be forced forwardly to a shaping bo; or throat 35 at the 'forward end of the mold box, andpreterably this shaping rboxv will have its upper wall inclined, as shown atk 36, and its side walls will also be tapered, as shown in dotted lines at 37,1in Figure fr, a removable cover 38`being provided for said shaping` box. The said b X 35 will serve `to shape and slightly compress the butter coming `from themold box, and this be); be made so as to divide thebar vertically and longitudinally into a plu-A` rality ci. bars, a bei; capable oit forming two bars being` shown in the present embodiment'. This. is accomplished by means ol a central lpartition 39, the rear end olfA which, is chamiered oil' or tapered, as at 4&0, in order to split and aid in 'shaping and solidilying the butter passing through the shaping'bozror throat. l

As the bar or bars ot butter issue from the shaping throat or box, they are delivered to a'carrier apron ll mountech'as shown',` upon suitable' rollers 42 carried upon an extension trame i3 of the machine, and in .order that the-bar or bars be cut into prints ot proper size and have stamped thereon any appropriate design or trade device, l provide a cuttingoil vand stamping device comprising a severing cutting ele ment 43C. here shown as a cross wire, mounted in depending arms lll et a cross bar 4:5., 'arried by swinging arms 4:5' which entend rearwardly and are supported in bearingsI in Figures l and 2, they are tree to rock and slide, stop pins 1l-8 being provided at the rear end ot said arms 4G so as to prevent their accidental. wthdii'awal from their bearings, The said arms 4.6 are spring-supported by spring plungers 49, one tor each ol" said arms, mounted in slotted barrels 50 iizred to the vmachine frame, the said spring' plu'n4 tending Aalways to hold the bars il@ and theprint cui ting-oil' devices elevated, as shown in liigure. l. y

Supported between vsaid balls le is a print block 52, the said print block b ,ing arranged in advance ot the print cut-oil mechanism, andl being made with a removable print- 12o ing` 'tace or block detachably secured by thumb screws 5B, so that the printing suri face be readily changed to suit the sign or mark ol'l a particular user. 21 han 54 is'provided by means et which the cutoliq and print block may be torced down wardly to out a print from the ribbon and mark it. i

ln order that the printsmay be regulated as to size, Iprovide a stopv and regulating bar 55 which is adjustably mounted on arms 56 pivotally connected at their rear ends to the bracketvarms 44. The said regulating plate 55 lies normally in the position shown in Figure 1and as the `butter bar feeds forward in the direction'of the arrows, it will' strike the bar 55, which will indicate to the operator that the bar has been obtruded from the shaping box a suflicient distance to give a print of the required size, whereupon he will manually force the print severing mechanism downwardly and cut off a print4v from the end of the butter bar, at the saine time marking said print, all asl shown in 'Figure 7. In order that the plate 55 will be shown in Figure 7, the print block head will engage an offset or shoulder 59 formed on the hanger 57, which hanger is of spring material, so that the shoulder 59 will snap over the end of the printA block, and as thev springs 49 raise the bars 46 and the cutting instrumentalities to their normal position,

the regulator bar 55 will be carried upwardly clear of the path of travel of the severed prints. After the carrier belt 41 has moved the printclear, as, for example, to the posi tion shown in dotted lines in Figure l, the

operator will simply knock oft" the hanger 57 so as to disengage the shoulder 59 and permit the stop and regulator bar to fall to the 4position shown in Figure l, lupheld by the end hook or offset 58. l

The carrier belt 4l is driven by a sprocket wheel 60, mounted on the shaft of the rear roller, said sprocket wheel 60 being connected by sprocket chain 61 with ai driving ysprocket 62 on the crank shaft l6`of the inachine, the forward end of the carrier belt 41 being mounted upon a roller 68 carried'in" spring bearings (see dotted lines) 64 with an adjusting device 65, by means of which the spring plates 66, which form the spring bear` yings for the roller 63, may be adjustedto properly tension the carrier belt.

It vis'obvious that the travel of the carrier belt must be suspended for the cutting off and printing of the block.v Otherwise the cut would be on an incline and the print would be smeared, which would result inan imperfect print of butter. In o-rder to intermittently suspend the travel ofthe belt 41, when the print cutting and stamping' mechanism heretofore described is operated, K

l provide a clutch mechanism between the sprocket 60 and the` shaft 67 of the drive roller 42, which is actuated whenever the print cutting mechanism is operated, to disconnect the sprocket wheel, which is continui ously driven bythe crank shaft, from theroller shaft. This clutchr mechanismA is' shown in Figures 2, 3 and 5, and vcomprises a housing 68 secured in any suitable manchine. The said yhousing is provided with a .70., y nei', as by screws 69, to the frame of the ma-` v `slot 70, as shown in Figure 2, through vhich slot projects zin-operating arm'7l eni gag-ing a ring 7 2, which ring 7 2 has radiallydisposed inwardly projecting pins 73 which engage a circumferential'groove in a clutch y i member 74 slidablyzinounted on the shaft 67 but keyed thereto so as 4to rotate therewith.

The said clutch member 7 4 has a ratchetface `75 opposed to a ratchet yface `76 on the sprocket wheel '60, which lrotates freely` on'v i the shaft 67 when in the idle position shown in Figure 2. Upon angular movement ofy the arm 71,'the ratchet member 74 will be n moved by the action of the cam slot 70 into and out of engagement with the ratchet on the sprocket wheelV 60, so as toeffect a driving engagement or a release of the shaft 67 f, f I' i and a consequent driving or stopping ofthe I roller 42 and carrier belt4l; I*

The said radially-disposed clutch operati-- iii-g arm 7l is connected with one of the cutoffl and print supporting sidev bars 46 byv means or a connection 77,` as clearly shown in Figures 1,4 and 5, in such a inannerfasthat on the downward movement of the cut ofiq and print block from the position shown 'i in Figure l tothe position shown in Figure 7, angular movement' to unship lthe clutch will be imparted to the radial arms 7l, `re-- leasing tlie shaft 67 andl its roller 42 from the continuously rotating sprocket 60, thus stopping the carrier belt 4l with the end of the butter4 bar in positiony to be cutoff and printed. l v i i g it will be noted that this unshippingof the vclutch and `stoppage pf the travel of Athe* carrier belt takes place when the bar-forining plunger is in retracted and yinactive vpnl' sition, 'so that when the carrier. belt is stopped for the cu'tfofl" of aprint,- there is no feeding forward of tlielbutter bar alongthe carrier bolt. ln other words, the butter bar will feed forward, under the infiu'ence'lo'fv the plunger, a suflicientdistance toobtrude the Vproper length of print, and will then be p retracted for a new thrust and during `tliat Immediately the cut off and stampingmechanism is re" leased, it will-beplautomatically raised by the spring supports 49, the clutchmeclianism vwill automatically couple the" roll andy its driving sprocket, and thelcarrier belt;

resume its travel, taking the print forward,` to any suitable delivery point Y The pivoted and sliding mounting of the `block with the butter prior to clutch release and stoppage ofthe carrier belt.

ln that term of the invention shown in Figures 8, 9 and l0, l have illustrated a dilierent form of shaping boi; or throat designed particularly Afor .filling cans with round prints of butter. 1in this adaptation of the machine, there will be no change in the mechanism for severing the butter from the mass or forcing it forward through the rmold box and throat, but the throat will be so adapted as to shape the rectangular- V endedl butter bar to circumferential form and deliver it to a round can. At the front of the shaping box is placed an insert 78, which forms the shaping throat having a round oriiice 79 therein with walls 8O sloping forwardly to the opening and arranged l about the sloping walls at regular intervals are a series ot projections 8l, the present rexample showing these as tour in number and arranged ninety degrees apart. Where 'he butter bar is of rectangular shape, these projections 8l will be so disposed as tocatch the corners lof the square bar, as illustrated in Figure 9, and their action will. be to split the cornersot the square bar and spread the surplus butter along their sloping walls and gradually shape it to the round contour of the discharge opening. The bar thus shaped and rounded `passes to a circumferential throat 82 on the projecting end of which the can 83 to be filled is slipped. As the advancing butter bar pushes the can from the throat 82, the bar-will be severed close to the top of the can in any suitable manner, either by a hand severing device or by so adapting the cut-oit mechanism shown in Figure 7 to this type of machine as that it can be forced downwardly to sever the but- Ater bar immediately the can leaves its supporting throat under the action of the advancing bar of butter.
